Specification of Letters Patent. Patented Jan. 10, 191 1.

Application filed March 24, 1910. Serial No. 551,'l343.

To all whom it may concern: I

Be it known that I, Mo-sn'on GUETT, a citizen of the United States, and a resident of Hartford, in the county of Hartford and State of Connecticut. have invented certain new and useful Improvements in Insulating- Covers for Electric Switches, of which the following is a specification.

In various forms of electric switchconstruction the movable switch mechanism is located in a receptacle supported by a toppla'te which rests on and issecured to the end walls of the receptacle.

This invention relates particularly to an insulating cover to fill the space between said top-plate and the side walls of the receptacle and more particularly to the maning cover pieces. Fig. 4 is a view in longi tudinal section illustrating a modification.

Referring to the drawings a-is the receptacle made usually from porcelain or like material and in which are mounted statiorfary contacts (not shown) which are connected with funding posts indicated at b b. Ledges c project from the side walls of the receptacle and are adapted to support the outer edge of the insulating cover pieces,

these ledges terminating below the upper face of the receptacle so that when the cover pieces are in place they will be flush with the face of the receptacle, as indicated in Fig. 2.

d is the top-plate from which the switch mechanism is supported; it rests on the end walls of the receptacle and is secured thereto. This top-plate has apertures for the push-buttons e. Depending fromthe topplate are the frame-plates f between which liainsni' the movable parts of the switch (not shown) are mounted. Sez:n "u the top-plate and extending laterally i, 21] each side thereof are the bracket-arms .Z----2 haw I ing upstanding pins 3-3, the ends of which are. s ightly enlarged.

10-l0 are the insulating cover piecesof a size and shape to fit between the toplate the other. These cover pieces are apertured' to fitover the pins 3--3 andthe s'ides' oi the apertures are reinforced by strips at will not slide over the enlarged ends of the pins 33 without springing a art sli htly. These stripsof-spring' materia form t e' securing means for holding the insulating cover pieces in place and as illustrated take the form of an elongated loop 15' the ends of which are secured to the cover pieces.

the switch can be completely installed and wired and the insulating cover pieces then placed in position, covering the entire face of the receptacle includin the binding est 6 b. This is made possi le by reason 0 the factthat the cover pieces do not interlock or project under the to -plate; they can be readily put in place an removed and form oughly protecting the electrical mechanism contained therein. i

By reference to Fig. 4 it will be noted that theend walls of the receptacle opposite the binding posts are cut down below the face of the.receptacle so that when a switch is installed in the side wall in the osition shown in Fig. 1 itwill be'possible or dirt and other materials'to drop into the receppieces. To guard against this I have proagainst the-binding posts as shown in Fig. 4.

1. The combination in from opposite .wall's thereo lateral yIeX- insulating cover ieces filling the spaces bi. tween said top-p ate and the side walls of said receptacle, and means forremovably securing said insulating cover pieces 053,111 brackets.

2. 'The combination in an electric switch and the side walls of the receptacle an extendingfrom one end of the receptacle to an effective closure. for the receptacle thor-' tending brackets carried by said top-plate,

spring material secured at their ends to'the cover pieces and spaced apart so that they The advantage of this construction is that tacle through the openings under the cover vided flanges depending from the under 'side of the cover pieces at each end and 1 ing an-electric switch with the receptacle and top-plate sup orted with the receptacle and a top-plate, of a bracket projecting laterally from each side of said top-plate, a closure member on each side of said top-plate and filling a space between the same and the walls of said receptacle, and means for removably securing said closures to said brackets.

3. In an electric switch-the combination with a receptacle and top-plate, brackets extending'laterally from said top-plate, pins upstanding from said brackets and having enlarged heads, closures filling the spaces between said top-plate and the side walls of said receptacle, and means carried by said closures adapted to yieldingly ei'nbrace said pins beneath the enlarged heads. Y

4. In an electric switch the combination with a receptacle and top-plate, of brackets with a receptacle and top-plate, of brackets extending laterally from both sides of said top-plate, upstanding pins on said brackets having enlarged'heads, closures filling the spaces between said top-plate and the side walls of said receptacle, apertures through said closures to receive said pins, and a pair ot springarms located on o posite sides of i said apertures and ada ted to spring over the enlarged ends of" sald pins, for the pur-- poses specified.

G. In an electric switch the combination Y with a receptacle and top-plate, of brackets extending laterally from both sides of said top-plate, pins upstanding from said brackets and having enlarged heads closures filling the spaces between said top-plate and the side walls of said receptacle, apertures through said closures to receive said pins, an. elongated loop secured to the vunder side of said closures, the side arms of said loo adapted to spring over the enlarged ends 0 said pins and interlock therewith.

7. In an electric switch the combination with a receptacle and top-plate, of closures adapted to fill-the spaces between said-topplate and-the walls of said receptacle, said top-plate and. closures covering the entire face of said receptacle from end to end thereof, means for removably securing said closures in place, and flanges depending from the under sides of said closures near each end thereof.
